J. S. ANDREWS WALL FURNACE Filed Sept. 27, 1926 INVEN TOR. JOHN J. ANDREWS BY ATTORNEY Patented Dec. 28, 1926.

UNITED STTES JOHN S. ANDREWS, OF LOS ANGELES, CALIFORNIA.

Application filed September 27, 192%.

My invention relates to wall furnaces for heating the rooms of a dwelling, oflice building, or the like, and the principal object of this invention is to provide improvements over my wall furnace disclosed in Patent No. 1,582,657.

The objects of my improvements are; first, to provide a heater or furnace of this class whereby the room, in or in connection with which the heater or furnace is installed, is ventilated at all times when the heater or furnace is in operation; second, to provide a furnace of this class whereby only the foul or heavier air of the room is directed outwardly when the furnace is in operation by reason of the positioning of the ventilating flue contiguous to the heating means, thereby causing the air or gases in the ventilating flue to be heated and to rise, and the heavier gases or air in the room to pass toward the furnace; third, to provide afurnace of this class whereby thorough circulation of the room may be had by fresh air passing upwardly at the back side of the heater and thence into the roomat the top of the heater, by heated air passing around the heated housing enclosing the heating unit, by hot gases of combustion from the heating unit, and by return of gases and air to the burner or heating means and to the exhaust vent; fourth, to provide a furnace of this class whereby a portion of the gases of combustion are immediately discharged to the atmosphere; fifth, to provide as a Whole a novelly constructed and arranged wall furnace of this class; and, sixth, to provide a furnace of this class which is simple and economical of construction, durable, efficient, safe and which will not readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a partial front elevational and partial sectional view of my furnace in its preferred form of construction in connec tion with a building wall, the portion in section being taken on the line 11 of Fig. 2; Fig. 2 is a sectional elevational View thereof Serial No. 137,889.

taken through 22 of Fig. 1, showing certain parts and portions in elevation to facilitate the illustration; Fig. 3 is a sectional View thereof taken through 3-3 of Fig. 1; and, Fig. 4 is a fragmentary sectional elevational view similar to that shown in Fig. 2 of a slightly modified form of construction of my furnace.

Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

My wall heater or furnace is preferably mounted in a recess R in one side of a,

building wall W, as shown in Figs. 2, 3 and a. The recess is preferably made between a pair of vertical studs S, as shown in Fig. 3. The lower portion of the recess R communicates with an opening 0 at the bottom of the wall through the floor.

My heater or furnace is self contained so that the same may be readily installed in the recess in the Wall and consists essentially of a face or front member 1, the outer housing 2, the inner housing 3, the heat reflecting housing 4, the burner 5 and the heating or burner elements 6.

The face or front member 1 is secured to the side of the wall provided with a recess by a flange 1 extending over the top and along the sides. The member 1 is provided with an outwardly extending inclined or beveled portion which extends outwardly from the flanges 1. In the inclined or beveled portion 1 at the top portion of the member 1, are provided a plurality of openings 1 for admitting heated fresh air into the room.

To the back side of the member or plate 1, are secured the forward edges of the top and side portions of the outer housing 2 which substantially fills the space of the recess R in the wall. The lower end of the housing 2 is open and communicates at all times with the opening 0 at the lower portion of the wall.

lVit-hin the housing 2 and similarly secured to the member or plate 1, is the inner housing 3 which is spaced at its back side, as well as lateral and top sides, from the corresponding sides of the housing 2, as shown in Figs. 2 and 3. The bottom of the inner housing 3 is closed to the opening O, but-the fresh air from the opening 0 passes between the opposed walls of the housings 2 and 3 and out of the openings 1 at. the upper portion of the front face member. On the back side oi the member or plate 1 is also sup ported the housing 4: which may be secured to the gaseous fuel burner 5 and extended upwardly therefrom. On the bur' er 5 and within the housing, a are mounted a plurality of radiant burner or heating elements 6 which substantially fill the space of the housing 4-. Said housing e is adapted to reflect the heat "from the heating elements 6 into the room. The housing l is preferably spaced at its back, top, bottom and lateral sides from the inner housing 3, as shown in Figs 1, 2 and 8.

in the front face of the member or plate 1, are provided openings over which are placed gratings or toraminous plates 7, 8 and 9, the first between the upper ends out the housings 3 and l, the second over the front side of the housing i and the latter between the lower ends or" the housings 3 and a, shown best in 2.

Near the lower portion and in the back side wall oi the housing 3, provided an opening 3 which is connected, by means of a vent duct 10 with the atmosphere, which duct may extend up through the wall and the root of the building. vent duct prei'erably fills the space between the housings 2 and 3 at their median lines, thus dividing the space between the two casings or housings into two parts, or more it desired.

The gases of combustion from the burner and radiant burner elements are forced into the room through the grating 8. m air from the room is drawn through the openings of the grating- 9 and directed into the space between the housings 3 and 4; and also into the vent duct 10, the fouler and heavier air entering the duct. As the air passes between the housings 3 and 4c, the same is heated and discharged as hot air through the grating l ll 3 1 into the room. The air from the room is also heated as same passes up the vent, therebv causing a draft and causing further circulation in the room. The air passing upwardly from the opening O between the housings 2 and 3 is also heated slightly, thus discharg ing heated fresh air into the room throng the openings 1. Thus the foul and heavier air is continuously driven out ot the room and replaced by heated pure air.

In the modified form oi construction shown in Fig. 4-, the upper end 01"- the heat reflecting casing or housing, 4, is directly connected with the vent duct 10 by means oi a duct or vent 11 whereby a certain amount of the fuel gases are driven 0e" into the atmosphere directly and whereby the gases in the vent 10 are also heated to a higher temperature so as to more readily discharge the same.

hough I have shown and described a particular construction, combination and arrangement of parts and portions and a certain modification thereoi, I do not wish to enses be limited to this particular construction, combination and arrangement, nor to the modification, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
